Operation and Programming Manual
14
Input‐Ouput Pin Control
You can set pins 11‐14 as inputs or outputs – it depends on the operating mode you select. In monitor
mode, all of the pins are limit outputs. In PID mode, pins 11, 12, and 13 are inputs, while pin 14 is an
output. By setting these Inputs and Outputs to suit the needs of the operating mode, as shown below,
you can take advantage of the LIMIT programming and PID the special functions for more efficient
operations. The standard configuration of these 4 opto‐coupler chips is for the PID mode.
Refer to appendix H for location of the opto‐couplers. Pin 6 on the opto‐coupler IC must be cut off. Refer
to Appendix P for external connections.
PID Mode Configuration
PIN 11 U13 INPUT TRANSPARENT
PIN 12 U12 INPUT HOLD ANALOG OUT
PIN 13 U11 INPUT HOLD TOTALIZER
PIN 14 U10 OUTPUT SETPOINT REACHED
Monitor Mode Configuration
PIN 11 U13 OUTPUT LIMIT 1
PIN 12 U12 OUTPUT LIMIT 2
PIN 13 U11 OUTPUT LIMIT 3
PIN 14 U10 OUTPUT LIMIT 4
To modify the standard configuration for the Monitor operating mode, change the three opto‐coupler
chips set for INPUT to OUTPUT. This enables the LIMIT outputs as shown above.
